Enhancing Surgical Preoperative Planning with 3D Interaction: A Comparative Study of Integral and Direct Mapping...

Area of Science:

• Surgical Planning
• Human-Computer Interaction
• Medical Imaging

Background:

• Preoperative planning is critical for surgical success, demanding precise placement of implants and targeting of anatomical structures.
• Three-dimensional (3D) interaction offers potential to improve surgical planning through direct manipulation of 3D models.
• Existing 3D interaction methods, integral mapping and direct mapping, lack comparative effectiveness studies.

Purpose of the Study:

• To compare the effectiveness of integral mapping and direct mapping 3D interaction for preoperative planning.
• To evaluate task performance and user workload using both 3D interaction methods.
• To assess the utility of a light field 3D display interaction system for pedicle screw placement planning.

Main Methods:

• Development of a light field 3D display interaction system incorporating both integral and direct mapping 3D interaction.
• Conducting a comparative study of task performance metrics.
• Assessing user workload using established evaluation methods.

Main Results:

• Direct mapping 3D interaction significantly reduced preoperative planning time compared to integral mapping.
• Users reported significantly lower workload when using direct mapping 3D interaction.
• The developed system demonstrated effectiveness in assisting with pedicle screw placement planning.

Conclusions:

• Direct mapping 3D interaction is a more effective method than integral mapping for improving efficiency and reducing user burden in surgical planning.
• The light field 3D display system with direct mapping shows promise for enhancing preoperative planning, particularly for complex procedures like pedicle screw fixation.
